Abstract

EN UN SISTEMA (10) DE BOMBA DE CALOR O DE REFRIGERACION ACCIONADO MEDIANTE UN COMPRESOR, LOS VALORES EXISTENTES DE AL MENOS DOS CANTIDADES VARIABLES, QUE CONSTAN DE LA TEMPERATURA O DE LA PRESION EN DIFERENTES LUGARES PRESELECCIONADOS (16, 17, 18, 19) EN EL SISTEMA (10), PUEDEN SER MEDIDOS. LOS VALORES MEDIDOS DE DICHAS CANTIDADES O AL MENOS UN VALOR DE AL MENOS UNA OTRA CANTIDAD VARIABLE, DERIVADOS DE DICHOS VALORES MEDIDOS, SE UTILIZAN PARA DETERMINAR LA CANTIDAD EXISTENTE DE FLUIDO DE TRABAJO EN EL SISTEMA (10) EN BASE A UNA RELACION PREVIAMENTE ESTABLECIDA ENTRE DICHA CANTIDAD Y EL VALOR O LOS VALORES RESPECTIVAMENTE, DE LA CANTIDAD O CANTIDADES UTILIZADAS. DE DETERMINAN AL MENOS DOS VALORES DIFERENTES PRELIMINARMENTE APROXIMADOS DE LA CANTIDAD DE FLUIDO DE TRABAJO MIENTRAS QUE SE UTILIZAN VALORES DE CANTIDADES VARIABLES AL MENOS PARCIALMENTE DIFERENTES, DESPUES DE LO CUAL SE DETERMINA UN VALOR RESULTANTE APROXIMADO EN BASE A DICHOS VALORES PRELIMINARES.
